Scientific Method
                                        Teacher Prep for Activity
                                        Photocopy “Human Impacts” worksheet and know which beach it is
                                        they are going to visit for their field trip. You may be able to find
                                        information on previous beach cleanup data on the NOAA website:
                                        (http://marinedebris.noaa.gov/); or the local Hawaii Wildlife Fund
                                        site: (www.wildhawai.org or email kahakai.cleanups@gmail.com).
                                        Photocopy the “Scientific Inquiry Process” handout. Find pictures of
                                        your local beach where the fieldtrip will be held.

                                        Background
                                        No additional background information is necessary.

                                        Procedure
                                             1. Prep the students on the scientific process: how to create a
                                                research question, hypothesis, and experimental procedure
                                                going step by step through the “Scientific Inquiry Process”
                                                handout. Let the students know that they will be going a field
                                                trip to collect their own marine debris during a beach cleanup
                                                at a local beach.
                                             2. Show the students a picture of the beach they will visit during
                                                the trip. Break the students into small groups and create a
                                                testable hypothesis about marine debris at that beach.

   3. Show the students the past data from the same beach (if possible) and have them create a
      research question and hypothesis based on past data or from the setup of the beach. A
      possible hypothesis could be: Cigarettes will be the most abundant type of marine debris
      at the beach (reasoning: based on past data that cigarettes were the most abundant type of
      debris found on beaches). OR More trash will be found near the shoreline than the
      parking lot.
   4. After each group has formed a hypothesis, have them think of how they would like to
      collect repeatable data for their study. Discuss the importance of repeatable data using
      the background from lesson 6.3. Ask them to write down several ways that they could
      collect their data, and then discuss if the strategies they thought of are possible to do in a
      single day or if it will prove their hypothesis.
   5. After they have decided upon an experimental design, have them write the final group
      consensus on their “Human Impacts” Worksheet.

Extension Activities
Many teachers enjoyed other marine-education activities, such as (if on Hawai‘i Island):
Hilo side -   Mokupapapa Discovery Center, Pacific Aquaculture & Resources Center
              (PACRC).
Kona side - Visit West Hawaii Explorations Academy (they have a touch tank
              for the kids and will give a tour of the school), Natural Energy Lab (NELHA)
              tours.

Before Data Collection:

Research Questions: (What is it that you would like to find out about marine
debris?)




Hypothesis: Write a complete sentence of what you think you will find. You
should be able to test your hypothesis. State your answer in a “If
……then…..because….” format)




Experimental Design: How will you collect your data? (Think of a method you
could use to test your hypothesis)

After Data Collection

Data Analysis: What did you find at the beach? Count and categorize your
findings. Using graph paper, chart your results. Summarize your results below.




Summary and Conclusions: Review your results. Does your data support or not
support your hypothesis? Explain.




Implications: From your findings, what do you recommend we do to malama
(care for) the marine environment? How can we share our results? Think of ideas
to share what you learned with your school and community.
